Doheny's Alkalinity Up Pool Alkalinity Increaser - Balanced pH Control

In this review of Doheny's Alkalinity Up, the reviewer focuses on backyard pool owners and maintenance DIYers who need a simple way to raise and stabilize total alkalinity before adjusting pH. The bottom line: this product does the one job it is meant for reliably - raising alkalinity to the recommended 80-120 ppm range - and because it is a straightforward sodium bicarbonate formula, it is predictable and easy to use for routine pool balancing.

Key Features

• Proudly Made in America: The product comes from a family-owned brand with over 50 years in the swimming pool supplies business, which offers continuity and known manufacturing practices.
• Alkalinity Increaser: Formulated to raise total alkalinity so you can better control pH and follow the correct sequence of adjustments.
• Reduces Corrosion and Irritation: Keeping alkalinity in the 80-120 ppm range helps reduce surface etching, eye irritation, and skin dryness when water chemistry is balanced.
• Active Ingredient: Contains sodium bicarbonate, a familiar and fast-acting alkalinity booster that is easy to dose and safe when used as directed.
• Multiple Packaging Options: Available in ready-to-use pouches and a 25 lb bucket for those who prefer larger quantities for seasonal maintenance.

Who It's For

This product is best for homeowners with in-ground or above-ground pools who perform regular water testing and need a reliable way to raise total alkalinity prior to pH adjustments. It suits DIY pool care routines and people who want a familiar chemistry (sodium bicarbonate) that behaves predictably when added to pool water.

Those who should look elsewhere include users who require a combined multi-step chemical product or concentrated industrial treatments; this is a single-purpose alkalinity increaser and not a pH-only or shock product. Also, if you prefer single-use packaging exclusively, check available pouch sizes before buying the 25 lb bucket.

Pros & Cons

Pros

• Reliable, fast-acting sodium bicarbonate formula that raises alkalinity effectively.
• Backed by a long-standing family-owned brand and domestic manufacturing.
• Available in small pouches or a 25 lb bucket to match usage needs and value considerations.

Cons

• Single-purpose chemistry means you still need separate products to adjust pH or sanitize.
• The 25 lb bucket may be more than needed for occasional pool owners preferring only small pouches.
